      First of all, Thank you very much for providing pfsense.

      I was able to configure dual wan for fail over and load balance without any problem.
      Pfsense is working wonderfully !!

      I have one problem.

      When I remove my DSL line (i.e. phone line) from DSL modem,
      It takes 15 seconds for pfsense to mark that interface as DOWN.

      Is it possible to decrease this time?
      (i.e. 1. by decreasing monitor poll interval [or] 2. decreasing the
      amount of time pfsense waits before it declares the interface down.)

      I play online poker. So when one link goes down/slow, I want to switch
      to other link with minimum amount of switch over time (i.e. like 5 seconds).

      I appreciate any help on this matter.

      Thanks,
      -Senthil Kumar

        Id be curious also if this is a variable that could be altered.  What is the default timeout when using failover?

          I've been wondering this myself.

          So is there any way to make the failover response time faster other than setting the check interval to a shorter time delay?

              @Coldfirex:

              Does anyone have any insight into this?

              Looking in my pfSense GUI -> Status -> System Logs -> Load balancer, I have lots of entries from something called "slbd".  A quick Google finds this: http://slbd.sourceforge.net/ Hmmm documentation a bit lacking, lets go for the source then.

              In pollers.c:

              static int tcp_read_timeout = 5000; /* in milliseconds /
              static int poll_interval = 5000; /
              in milliseconds */

              I am not a programmer though and this may be overrideable but I can't see anything in the config files either.

              So, I would guess not.  Unless you change the definitions above and roll your own slbd.
